Part 2: What makes QDX HealthID different than other Health Status
Post# of 22456
Opinions in the following post are author's speculation and not presented as fact.
On April 13, 2020 Quantum Materials Corp announced QDX™ HealthID, a blockchain-based service that provides end-to-end visibility to support testing and immunization for infectious diseases on a global scale.
Late last summer, QMC started developing and was soon marketing a secure authenticity platform leveraging nanoparticles as a track/trace mechanism to verify the origin of products in order to mitigate counterfeiting. The Anti-Counterfeiting Distributed Ledger Technology (DLT) is a decentralized blockchain service for supply chains.
QMC adapted their Anti-Counterfeiting DLT to the specific use case of a Health Status Reporter.The important commonality is that QMC uses the same secure authenticity platform for QDX HealthID. Therefore it also uses nanoparticles in its Authenticity Protocol. Anti-Counterfeiting efforts are typically aimed at either Product Security or Identity Management. There are few other competing systems using nanoparticles for these purposes.
In the QDX HealthID Product Brief 2.2, QMC further discusses the use of nanoparticles in their product –
“Support for multiple methods of determining individual and product authenticity, such as integration with open-source Auth0 mechanisms, capture of QR codes and tight integration with authentication products incorporating QDX™ Dot optical signatures.”
Quantum Dots in an optical signature could have different colors, different quantities, different patterns and other combinations of differentiation. There are literally tens of billions of possible combinations to use to foil counterfeiting. An optical signature is read by an optical reader.
The concept of immutability is an absolute. Typical optical codes, for example, non-QD embedded QR Codes, are read and digitized and encrypted into a Blockchain. This is the current practice and it is not perfect, but it is the most widely used method of capturing data from the reader into a blockchain. There are possible ways to hack some encryption now and at some point Quantum Computing will be able to hack any encryption relatively easily and quickly. So any system set up today that does not have a way to prevent future-Quantum Computing from hacking your blockchain is future-vulnerable and not immutable. The blockchain would need to be scrapped and a new Quantum Computing-resistant system installed.
QMC and QDX HealthID claim to have an immutable blockchain. QMC also says it can digitize their optical signature and encrypt and integrate it into the Blockchain just like everyone else. If QMC does that, it is relying on the uniqueness of its optical code with billions of combinations of quantum dots to give security.
The question is - Can it be done better? Is there a way to avoid “future-vulnerable” by not encrypting but using a different method? A method that cannot be hacked?
Do you remember ever seeing movies with the protagonists each holding half a torn picture or playing card, so that two people could meet and match up their halves to identify themselves? What if QMC wrote software to take a 3-dimension picture, in some way, of the QD Optical Signature that does not digitize or encrypt it, per se, but leaves it as a readable signature that can be verified optically (the other half of the photo)? This would reside in the blockchain as an object instead of a code, and therefore not be future hackable. How do you hack a picture that would be difficult to even describe, and made of tens of billions of parts?
That’s one example of what can be done with quantum dots. There are other methods. There are many ways to read quantum dots, many ways to vary quantity, color, patterns of quantum dots, and many ways to store quantum dots with those variations. I would say that QMC can adapt to the clients’ needs for security in many ways. And again, this is all my own speculation on my own DD.
